APPARATUS FOR REDUCING SOAP MATERIALS TO POWDER.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed October 25, 1907. Serial No. 399,095.

T 0 all whom it may concern:

Be it known that I, WILLIAM B. ALLBRIGHT, a citizen'of the UnitedStates, residing in Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Apparatus for,Reducing Soap Materials to Powder, of which the following is aspecification.

ThlS invention relates to apparatus intended for use in reducing soap tothe form of powder, and is an improvement upon apparatus previously usedfor that purpose.

The nature of the invention is fu 1y disclosed below, and will also beunderstood from the accompanying drawings, in which- Figure 1 is a lanof the invention partly in section, Fig. 2 1s a longitudinal verticalsection, and Fig. 3 is a transverse vertical section.

In said drawing, 5 represents a bottomless casing surrounding themechanism of the invention, and'having close fitting doors 6, 6, at eachside.

7 is a-base frame supporting the casing and to which it is bolted, saidframe being secured to the floor by bolts 8. Above the casing is atrough 9 arranged longitudinally of the casing, and into this trough ahop er 10, located over its center, discharges the b consisting of mixedliquid soap and soda ash, which are formed in the mixer 11 locatedimmediately over the hopper. As the particular construction of thismixer forms no part of the present invention, I do not illustrate ordescribe it in detail. Suflice it to say, that it agitates the materialsuntil they unite and form balls or lumps, in which form they aresubjected to the action of the disintegrating mechanism described below.

In the trough 9 is a revolving conveyer shaft 12, constructed to feed inboth directions from the hopper mouth, and thus to conduct the balls orlumps of the mixed materials to the conducting passages or chutes 13 atthe ends of the casing 5, by which they are fed into the casing. Theconveyer shaft is actuated by the be t pulley 14.

Extending through the casing is a rapidly driven shaft 15 driven by thepulleys 16, and supported in bearings 17 on the standards 18 locatedoutside the casing. This shaft is provided with arms 19 carrying attheir outer ends plates 20 with saw tooth outer edges adapted todisintegrate the lumpy maalls or lumps terial, and outside of and inclose proximity to the path of the toothed edges of the plates is asurrounding stationary screen made u of sections 21 of erforated metal.This screen is supported by end frames 22 and intermediate frames 23.All said frames have projecting flanges 24 around which the screensections may be bent and confined by stiff metal bands 25, havin theirends bent outward and bolted toget er as at 26, and the pair of bands atopposite edges of each screen section are tied together by strips 27.The frames 22 and 23 all extend down to and are supported on the baseframe. The bands 25 abut closely against the frames, so that the screenforms a complete inclosure from which none of the material can escapeexcept through the meshes of the screen. The ends of the casing areclosed tight by said end frames 22, in which are formed openings for theinlets 13 and for the shaft 15.

The balls or lumps received from the mixer are confined by the screenwithin the field of action of the toothed beaters until they are reducedto powder, and the owder then passes through the screen into t e outerpart of the casing and falls through the bottom of the same into asuitable receptacle, or into the packages in which the same is to bemarketed.

The dust developed by the reducing process described is given exit fromthe casing by the pipe 32 opening from its to To prevent the feeding ofthe material aster than the disintegrating mechanism can reduce thesame, I place a gate 28 in each of the feed passages 13, which can beadjusted whenever necessary by the handles 29. The casing doors arehinged at 30, and are provided with ring pulls 31 whereby they may beopened. The vent 32 by which the dust is allowed to escape from thecasing is also very beneficial, particularly in damp weather, as itallows the moisture, as well as the dust, to escape.

I claim:

1. The apparatus for reducing soap balls or lumps to powder, embracing amixer a conveyer feeding the balls from the mixer to the reducingmechanism, and reducing mechanism consisting of a casing, revolvingsharp toothed beaters in the casing, and a screen surrounding thebeaters, said casing having a dust outlet and an outlet for the powderedsoap.

2. The apparatus for reducing soap balls or lumps to powder, embracing amixer a conveyer feeding the balls from the mixer, a passage having avalve and extending from 5 the conveyer to the reducing mechanism,

and reducing mechanism consisting of a casing, revolving sharp toothedboaters in the casing, and a screen surrounding the heaters, said casinghaving a dust outlet and an outlet i or the powdered soap.
